Re: 3DO Doom succesfully compiled (but no way to run it)

If you want to change the flushing value, at threedo.c there is #define CCBTotal 0x200. I have managed to set it to something like 0x1000 and still fits in memory. I also managed to count the CCBs per frame by increasing a counter in every function that adds ccbs, and it can go from 240 to 1500 in w...

Re: 3DO Doom succesfully compiled (but no way to run it)

I have seen the video, I am not sure why the monsters are so slow, don't know if it's the ram or some other bottleneck. If it was the memory, it would have possibly crashed? Although there is a place in code where it's rendering all the stuff in batches, and when it reaches a certain amount of cels,...

Re: How 3D on the 3DO really works... ?

Btw, the code I posted about memory, won't report anything in Doom. The reason is, another memory manager is used in Burgerlib that cancels the one from the system. But the good news is there is also a function to get the available memory in Burgerlib. And it's much easier. You only need to add two ...

Re: How 3D on the 3DO really works... ?

Welcome aboard, Optimus! I'm adding a new types of monsters and other objects in Doom. I think that at some point RAM became full (some freezes and frequent CD reading occurs). Could you make some kind of progress bar for RAM? It will be very helpful. Now I'm thinking how to use sounds quickly with...

In my hobby I used to collect retro computers and console, write code for few of them, usually demoscene stuff, although I am more interested for homebrew gamedev ...

Re: How 3D on the 3DO really works... ?

Hello all! I managed to approve my account finally. Thanks for posting the link to my entry btw. It's very exciting for me to come back to 3DO coding. I have few plans for that future. One is to try to understand everything about the Cel structure, make some performance benchmarks I have in mind, an...
